2.2. BLEDK3 Tools and Materials

BLEDK3 is one of the IS1870SF BLE application firmware which support the following features:

- BLE UART Transparent

- BLE GATT Based Transceiver

- Beacon

2.2.1 BLEDK3 Release Note

Read first “BLEDK3 Release Note “, it describes supported software features for the BLEDK3.

2.2.2 Flash Download Tool

If necessary, new BLEDK3 firmware can be updated with the “ISupdate Firmware Update Tool”. The

download procedure is described in “BM70BLES1FC2_EVB User Guide”.

Figure 2: ISupdate Firmware Update Tool

Note: Verify BLEDK3 device features in the “Release Note” Document. If an update to newer firmware version is necessary, then the flash code

should be downloaded first, before the UI parameters are loaded. As the flash update process could overwrite the UI parameter configuration.

2.2.3 UI Tool

Configure the UI parameter by UI tool, then download the UI table to flash in BM70 module.

- UI tool user guide: “User Guide of BLEDK3 UI Tool”

- UI table download procedure: ” BM70BLES1FC2_EVB User Guide”

- UI table for mass production: Save UI table, the *.hex file is for mass production.

2.2.4 UART Command Tool

UART command set of BLEDK3 is described in “BLEDK3 UART command set” document.

BLEDK3 uart command tool (windows based) operates on either auto pattern or manual pattern.

- Auto pattern, BLEDK3 will be executed base on internal state machine that can be configured by UI tool, it only

supports BLE Slave and build-in services.

- Manual pattern, BLEDK3 will be executed base on MCU command totally, it supports both BLE Master and BLE

slave by using UART protocol with MCU. And appended services only can operate in manual pattern.

Supported tools and user menu:

- Auto Pattern: “BLEDK3 Auto Pattern Test Tool.exe”, ”User Guide of BLEDK3 Auto Pattern Tool”

- Manual Pattern: “BLEDK3 Manual Test Tool.exe”, ”User Guide of BLEDK3 Manual Pattern Tool”

Please read the “BM70BLES1FC2_EVB User Guide” for set up the test environment.

In the connection diagram, PC and the tool is acted as a MCU role to communicate with BM70 module by UART

command set.

For MP (Mass Production) test of BM70BLES1FC2 or IS1870SF-102, an adapter board named

“Victoria Level Shift” (Shown in figure 4-1) is required to add on the CON1 connector of the Victoria

test board. This board provides the function of bypassing the UART TX/RX voltage level to VBAT

during voltage calibration.
